Changing radio access technologies to connect to a network

ABSTRACT

A light-weight solution for media handovers between different Radio Access Technologies (RAT) is provided. A user may switch from Wi-Fi to Cellular Data (e.g., LTE/4G/3G/ . . . ), from Cellular data to Wi-Fi, and the like. In contrast to a “make-before-break” design for switching between RATs, the technologies described herein are a “break-before-make” design. When a change in a RAT is detected, an application on the computing device utilizing the connection is notified of the change. Instead of removing connection information, the connection is maintained for a configurable period of time such that the application can re-register with the network to continue the communication session. During a transition to a second RAT, the application provides one or more notifications to the user of the change in RAT. For instance, a graphical user interface (GUI) can be displayed showing the change and/or a tone can be played indicating the change in the RAT.

CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of and claims priority to U.S.application Ser. No. 16/209,829, filed on Dec. 4, 2018 and entitled“Changing Radio Access Technologies to Connect to a Network,” theentirety of which is incorporated herein by reference.

BACKGROUND

Mobile networks are expanding rapidly. For example, not only are 4G-LTEnetworks expanding, wireless service providers are starting to deploy 5Gnetworks. As these networks expand and provide more bandwidth at higherspeeds, real time communication (RTC) between computing devices isbecoming more typical. For example, there are applications that allowusers to video chat, share media, and the like. When a user switchesfrom one type of radio access technology (RAT) to another type of RAT(e.g., Wi-Fi to 4G-LTE), the communication between applications can beinterrupted. This interruption can be disruptive to the communicationsession.

DETAILED DESCRIPTION

Described herein are techniques and systems for changing radio accesstechnologies to connect to a network. Using techniques described herein,a light-weight solution for media handovers between different RadioAccess Technologies (RAT) is provided. For example, a user may switchfrom Wi-Fi to Cellular Data (e.g., LTE/4G/3G/ . . . ), Cellular data toWi-Fi, and the like using the technologies described. Generally, a RATis the underlying physical connection method for a radio-basedcommunication network, such as utilized within a network associated witha wireless service provider. Many computing devices (e.g., mobilephones) support several RATs (e.g., Wi-Fi, and 3G, 4G, LTE, 5G).

In contrast to a “make-before-break” design that may be utilized forswitching between RATs, the technologies described herein describe a“break-before-make”design. The “break-before-make” system describedherein is a more light-weight solution (e.g., using fewer computationalresources and/or communication bandwidth) as compared to a“make-before-break” solution. According to some configurations, when achange in a RAT is detected, an application on the computing deviceutilizing the connection is notified of the change. Instead of thenetwork removing the connection data associated with the applicationupon detecting the loss of connectivity with the network, connectiondata associated with the computing device is maintained by the networkfor a configurable period of time. During this time, the application canrequest to re-register for a second connection such that the media usedby the application can continue using the second connection that isassociated with the new RAT.

According to some examples, one or more notifications are provided bythe computing device to indicate the change in the RAT the applicationand/or to the user of the computing device. For instance, a graphicaluser interface (GUI) can be displayed showing the change and/or a tonecan be played indicating the change in the RAT. As an example, if afirst user is connected to a network via Wi-Fi and is on a call with asecond user, then when the first user moves away from Wi-Fi (e.g., losesconnection to the Wi-Fi), there is a break in the connection and achange in RAT. At this time, the application and/or the user can bepresented with a user interface and/or notification indicating the breakin the connection and the move to the new RAT (e.g., Wi-Fi to 5G, 4G to5G). The application is notified of the break in connection such thatthe application has time to re-register such that the application isconnected using the new RAT. As such, the user is informed that theconnection is re-establishing with a different RAT. More details areprovided below with regard to FIGS. 1-5 .

FIG. 1 is a block diagram showing an illustrative environment 100 forchanging radio access technologies to connect to a network associatedwith a wireless service provider. The environment 100 may include anetwork 102 that is operated by a wireless service provider. Theenvironment 100 is illustrated in simplified form and may include manymore components.

The network 102 may include one or more base stations 104 and one ormore service nodes 106. A base station 104 may handle traffic andsignals between electronic devices, such as the computing devices 108Aand 108B, and a core network of the network 102. For example, the basestation 104 may perform the transcoding of speech channels, allocationof radio channels to electronic device, paging, transmission andreception of voice and data, as well as other functions. The basestation 104 may include several base transceiver stations (BTS), eachBTS may include a transceiver, antenna, and additional network switchand control equipment that provide a network cell for facilitatingwireless communication between computing devices and the core network ofthe network 102. In some examples, the base station 104 can include aneNodeB and/or a gNodeB.

The network 102 may be responsible for routing voice communication(s) toother networks, as well as routing data communication(s) to externalpacket switched networks, such as the Internet. For example, the one ormore service nodes 106 may be a Gateway GPRS Support Node (GGSN) oranother equivalent node. According to some configurations, the one ormore service nodes includes a node configured to perform operationsrelating to RATs. One or more of the service nodes 106A can also beconfigured as a Policy and Charging Rules Function (PCRF) node thatutilized to enforce policy rules of the network, or some other type ofnode.

The RAT node 106C can be configured to perform operations as describedherein relating to a computing device, such as the computing device 108Achanging from a cellular (e.g., 4G-LTE, 5G, . . . ) to Wi-Fi, from Wi-Fito another RAT, and the like. In some examples, the computing device108A may temporarily lose connection to one RAT, and then re-establishconnection to the same RAT. More details are provided below. The PCRFnode can be configured to automatically make policy decisions for eachsubscriber active on the network. For example, the PCRF may be utilizedto allocate bandwidth of the network as well as provide different levelsof service to different computing devices on the network. Additionally,some data can be prioritized within the network.

The computing devices 108A and 108B may be a smart phone, a personaldigital assistant, a netbook, a laptop computer, and/or anotherelectronic that is capable of sending and/or receiving voice or data viathe network 102 and/or a Wi-Fi network.

In some configurations, one or more of the service nodes 106 may beconfigured as one or more application servers that provide support forone more applications, such as application 110. While the service nodes106 are illustrated within the network 102, one or more other computingdevices may be located outside of the network 102. For example, anapplication server, or some other server or device, may be connected tothe network 102 via one or more external packet switched networks, suchas the Internet.

According to some configurations, a telephony client application, suchas application 110, on the computing device 108 may establish datacommunication with the network 102 through a data connection to the basestation 104. The base station 104 may route a communication from thecommunication device 108 through the core network via the service nodes106. In such instances, the service nodes 106 may be capable ofperforming subscriber profile insertion with respect to data trafficbetween the application 110 on the computing device 108 and theapplication server. For example, the application 110 may be anapplication that sends data to another computing device, such as tocomputing device 108B.

When a communication request arrives at the network 102, one or more ofthe service nodes 106 may determine the originating number for thecommunication as well as the computing devices to send thecommunication. According to some configurations, the application 110 onthe computing device 108 may connect to the service nodes 106, or someother component such as an application server, via the Internet 112. Insuch instances, the application 110 may connect to the Internet 112 viaWi-Fi access point 114A. Accordingly, data traffic from the application110 may be routed to the service nodes 106 by the gateway 116 of thenetwork 102. Similarly, device 108B may connect to the Internet 112 viaaccess point 114B.

In either case, the computing device 108, such as the computing device108 a, requests to make a communication with a destination numberassociated with one or more computing devices. The network 102 receivesthe request and, in some cases, may authenticate the user and/or thecomputing device. For example, the service nodes 106 may authenticatethe computing device 108. In some cases, the service nodes 106 may querya database, or some other data store or memory, to determine theoriginating number and the computing devices associated with therequested destination number.

In some configurations, the RAT node 106C is configured to providefunctionality associated with the switching of a first RAT used by acomputing device to connect to at time T1 to a second RAT used by thecomputing device at time T2 to connect to the network 102. Asillustrated in FIG. 1 , computing device 108A is utilizing a first RATat time T1, and at time T2 transitions to a second RAT to connect to thenetwork 102. For example, a user associated with computing device 108Amay switch from Cellular Data (e.g., LTE/4G/3G/ . . . ), to Wi-Fi data.As briefly discussed above, computing devices 108 may support severalRATs (e.g., Wi-Fi, and 3G, 4G, LTE, 5G).

In contrast to a “make-before-break” design for switching between RATs(or re-establishing connection to a same RAT), the technologiesdescribed herein describe a “break-before-make” design. The“break-before-make” system described herein is a more light-weightsolution as compared to a “make-before-break” solution. According tosome configurations, when a change in a RAT by a computing device 108connected to the network 102 is detected, the application 110 isnotified of the change. For example, a component on computing device108A may notify the application 110 of the change in the RAT.

Instead of immediately terminating the connection to the application 110upon detecting that the computing device 108A is no longer connected tothe network 102 (e.g., due to the RAT change), connection dataassociated with the connection to the computing device 108A ismaintained for a configurable period of time. For example, the RAT node106C may maintain connection data for the registration requestassociated with the first RAT. During this time the connection data ismaintained, the application 110 can re-register to request a new secondconnection utilizing a different (i.e. second) RAT (or in some cases,re-establishing a connection with the same RAT) such that the media useby the application 110 can continue.

According to some examples, one or more notifications are provided viathe UI 122 by the computing device 108A to indicate the change in RAT tothe user of the computing device. For instance, a graphical userinterface (GUI) 122 can be displayed showing the change and/or a tonecan be played indicating the change in the RAT. Providing one or morenotifications of the change allows the user of the computing device toidentify a break in connection for the application. For example, if auser is using a video application to communicate with another videoapplication, and the connection changes from a cellular connection toWi-Fi, the user will know that any delay is caused by the change in theRAT. FIG. 2 shows illustrative user interfaces and notifications thatcan be provided to indicate the change in RAT to the user associatedwith the computing device 108.

In the example illustrated in FIG. 1 , a user is connected to a networkvia a cellular connection and is on a call with second user. When thenuser moves within range of a Wi-Fi network, there may be a break in thecellular connection and a change in the RAT. Upon detecting the changein the RAT, the computing device 108A provides a display (e.g., on thescreen of computing device 108A) indicating the break in the connectionand the move to the new RAT (e.g., 4G-LTE to Wi-Fi). The application 110is also notified of the break in connection such that the application110 has time to re-register with the network 102 and the application isconnected to the network 102 using the new RAT. In some configurations,a component of computing device 108A provides the notification. If theapplication was not notified of the change in the RAT, the connectionwith the mobile network 102 would terminate and the application 110 maynot readily be able to determine the cause of the termination of theconnection. Notifying the application of the change in the RAT allowsthe application 110 to decide as to whether to send a registrationrequest 120 associated with the connection to the new RAT, or not. Oncethe application 110 has received the notification, the application 110can also inform the user that the connection is re-establishing with thesame or a different RAT.

According to some configurations, WebRTC-based sockets are used forconnections between different applications 110 and computing devices108. In some examples, the application 110 receives a sessiondescription from a browser (or some other application) and thencommunicates with the other applications connected to network 102 usingpeer-to-peer communication.

FIG. 2 illustrates screen diagrams 200 showing example graphical UIs202A-202D that display data relating to providing an indication that thedevice is switching to a different RAT. The UIs 202A-202D may begenerated by the application 110, shown in FIG. 1 , or by some othercomputing device (e.g., one or more service nodes 106 within network102) or some other component or computing device. In someconfigurations, the UIs 204 are presented on a computing device, such asthe computing device 108A, by an application, such as application 110,or a web browser application.

As illustrated in FIG. 2 , the UIs 202A-202D include a display of themessage 204A-204D indicating the change in the RAT. In the currentexamples, the message 204A displayed within UI 202A indicates that theapplication 110 is switching from a Wi-Fi connection to a cellularconnection (e.g., 4G-LTE, 5G, . . . ). The messages 204A-204D are merelyillustrative and can be any type of message or indication that notifiesa user of the change in networks.

The message 204B displayed within UI 202B indicates that the application110 is switching from a cellular connection to a Wi-Fi connection. Asdiscussed above, in some configurations, a sound (or some other type ofnotification) can also be presented to a user. In the current example,one or more sounds are output as indicated by element 208. The soundsmay be one or more tones, a voice message, and the like.

The message 204C displayed within UI 202C indicates that the application110 is switching from a Wi-Fi connection to a cellular connection (e.g.,4G-LTE, 5G, . . . ). As illustrated, the UI 202C includes a selectableUI element 206A that allows a user to indicate not to switch to acellular connection (or some other type of network). For example, theuser may not desire to switch due to security concerns, cost, and thelike.

The message 204D displayed within UI 202D indicates that the application110 is switching from a cellular connection (e.g., 4G-LTE, 5G, . . . )to an untrusted network. For instance, the new connection may be apublic Wi-Fi that may not provide the security desired by the user. Asillustrated, the UI 202D includes a selectable UI element 206A thatallows a user to indicate not to switch to the untrusted network. Manyother types of UIs can be provided to indicate the change in the RAT.

In some examples, the server304 includes or is communicatively connected with an IWF or other devicebridging networks, e.g., LTE, 3G, and POTS networks. In some examples,the server 304 can bridge SS7 traffic from the PSTN into the network306, e.g., permitting PSTN customers to place calls to cellularcustomers and vice versa.

In some examples, the cellular network 308 and the data network 310 cancarry voice or data. For example, the data network 310 can carry voicetraffic using VoIP or other technologies as well as data traffic, or thecellular network 308 can carry data packets using HSPA, LTE, or othertechnologies as well as voice traffic. Some cellular networks 308 carryboth data and voice in a PS format. For example, many LTE networks carryvoice traffic in data packets according to the VoLTE standard.

In the flow diagrams of FIGS. 4 and 5 , each block represents one ormore operations that can be implemented in hardware, software, or acombination thereof. In the context of software, the blocks representcomputer-executable instructions that, when executed by one or moreprocessors, cause the processors to perform the recited operations.Generally, computer-executable instructions include routines, programs,objects, components, data structures, and the like that performparticular functions or implement particular abstract data types. Theorder in which the blocks are described is not intended to be construedas a limitation, and any number of the described operations can becombined in any order and/or in parallel to implement the processes. Fordiscussion purposes, the processes 400 and 500 are described withreference to the systems 100, and 300, as described above, althoughother models, frameworks, systems and environments may implement theseprocesses.

FIG. 4 is a flow diagram of an example process 400 that includesnotifying an application 110 of a change to a different radio accesstechnology in a mobile network, according to some implementations. Theprocess 400 may be performed by one or more computing devices, such asthe computing devices described with regard to FIGS. 1 and 3 .

At 402, a first RAT is used to receive data from an application 110associated with a first computing device 108A. As discussed above, thecomputing device 108A may be connected to the network 102 associatedwith a wireless service provider using one of a plurality of RATs. Forexample, the first computing device may connect to the network usingWi-Fi, 4G-LTE, 5G, and the like.

At 404, the change in RAT is detected. As discussed above, a computingdevice 108A, may disconnect from one RAT by moving out of range of theRAT, manually disconnecting from the RAT, or losing connectivity to theRAT by some other way. In some configurations, the computing device 108Anotifies one or more of the service nodes 106 of the change in the RAT.

At 406, the application 110 is notified of the change to the RAT. Asdiscussed above, the RAT change notifier component 340 may notify theapplication 110 of the pending change or change to the RAT utilized bythe computing device 108A.

At 408, the connection information to the application 408 is maintainedby the network 102 for a period of time. As discussed above, instead ofterminating any connections to the application upon the change,connection data associated with the registration of the application 110via the first RAT is maintained for a configurable period of time suchthat the application 110 has time to re-register with the network 102using the new RAT. Since the connection data is maintained, the network102 is able to identify that the application 110 was connected to thenetwork 102 before the change in the RAT.

At 410, one or more notifications are provided to the application 110 ofthe RAT change. As discussed in more detail below with regard to FIG. 5, a graphical user interface, audio notification, and/or some other typeof notification may be provided (e.g., vibrating, flashing, . . . ) toindicate to the user of the computing device 108A of the change in RAT.

At 412, a re-registration request is received from the application 110.As discussed above, the application 110 is provided time to re-registerto use the second connection established using the different RAT.

At 414, the application 110 is connected to the second RAT such that theapplication can continue the communication session with one or moreother applications associated with one or more other computing devices.

FIG. 5 is a flow diagram of an example process 500 that includesproviding one or more notifications in response to detecting a change ina radio access technology. The process 500 may be performed by one ormore computing devices, such as the computing devices described withregard to FIGS. 1 and 3 .

At 502, data is provided to the application 110 associated with the RATchange. As discussed above, in some configurations, the RAT notificationcomponent 340 notifies the application 110 of the RAT change.

At 504, a user interface indicating the RAT change is caused to bedisplayed. As discussed above, the RAT component 332 can provide dataassociated with a GUI, such as UIs 204A-204D as illustrated in FIG. 3 ,to the application 110. In other examples, the RAT notificationcomponent 340 can provide the data associated with the UI. Theapplication 110, or some other application, on computing device 108A mayutilize the data to display the user interface 202.

At 506, a sound notification, or some other type of notification, may beprovided. As discussed above, a sound notification such as a beep(s), orsome other auditory output can be output by the computing device 108A.In some configurations, some other type of notification can be provided,such as, but not limited to vibration, flashing, and the like.

The various techniques described above are assumed in the given examplesto be implemented in the general context of computer-executableinstructions or software, such as program components, that are stored incomputer-readable storage and executed by the processor(s) of one ormore computers or other devices such as those illustrated in thefigures.
